Morty used a Gastly to battle Ash in from Ghost to Ghost. A pair of Gastly were among a group of Ghost Pokémon living in an abandoned mine in Fear Factor Phony. The Ghost Pokémon couldn't stand the partying Psychic Pokémon that lived in the nearby town, so they created a Haunter-like illusion to scare everyone away.

Red's Bulbasaur manages to defeat it by sucking up the surrounding air with its bulb, along with Gastly's gaseous form, and expelling it in a SolarBeam.
